sPECIFICATION forming part of Letters Patent No. 718,047, dated January 6, 1903.

Application filed March 14, 1900. Serial No. 8,577. (No model.)

To ctZZ whom it may concern:

Be it knownthat I, EVERETT J. CAMPBELL, of Elmira, in the county of Chemung, in the State of New York, have invented new and 5 useful Improvements in Stovepipe-Collars, of which the following, taken in connection with the accompanying drawings, is a full, clear, and exact description.

This invention relates to improvements in stovepipes, having more partiular reference to the removable and adjustable collar which is placed thereon for the purpose of shortening or elongating the length of the pipe.

My object is to produce a device in the form I of an adjust-able collar which may be placed upon a length of pipe, providing it with means for easily and readily tightening it upon the pipe, so that it may be moved longitudinally thereon and secured at any point desired, and

which collar serves as a bearing for the adjacent length of pipe, so that the two lengths may be either lengthened or shortened to suit the requirements in hand.

My invention consists in the several other new and novel features of construction and operation which are hereinafter described, and more specifically set forth in the claim hereunto annexed. It is constructed as follows, reference being had to the accompanying drawings, in which- Figure 1 shows a length of pipe provided with my improved collar just before it has been secured to the pipe and the adjacent length of pipe just before it comes into en- 3 5 gagement with the said collar. Fig. 2 shows two lengths of pipe secured together with my improved collar, one section of the pipe being broken away. Fig. 3 is a similar view, enlarged, showing the removable length of pipe in section. Fig. 4 is a cross-section on line mm, Fig. 3. Fig. 5 is a cross-section of the pipe to which the collar is secured. Fig. 61s

a cross-section of the pipe which passes over the collar.

Similar letters of reference indicate corresponding parts.

0t and b are two lengths of pipe, the length a being slightly smaller than the pipe I) and has its lap or joint folded upon the inside, as shown at a, so as to leave the periphery free and unencumbered by a seam. To this por- .movement of said levers.

tion of the pipe I secure the collar 1), which comprises a strip of sheet metal 0, bent into the form of a short piece of pipe, having one end corrugated, as shown at c, and the other end provided with an annular bead d, formed by a rimmingmachine or in any other suitable manner, the lateral ends lapping each other, as shown at at, said head forming an abutting shoulder for engaging the adjacent end of the outer pipe-section and limiting its down ward movement. Adjacent to the meeting edges I secure a locking device, as a toggle connection, which comprises two levers e and 6, each being pivoted at the pointfand f, respectively, to the collar 1) and preferably to the head 61, as shown in Fig. 1. The leverie is extended beyond its point of union with the lever e and is provided with a slotway 9 upon its lower face and pivoted at g to the lever e, at one side of its pivotf, so that by operating the lover a the lateral edges of the collar b are drawn together and hold fast to the length of the pipe, the bolt f passing into the slotway g when the parts are drawn together, as shown in Figs. 2 and 3, and the lever 9 being provided with a stopshoulderl for engaging the upper face of the lever when open or closed for limiting the r To operate my invention for the purpose of lengthening or shortening the length formed by the two lengths of pipe, I first raise the lever 6', as shown in Fig. 1, so as to loosen the collar 1). I am then enabled to slide the 001- lar at any point desired upon the length a. Having done this, I press the lever 6 down to the position shown in Figs. 2 and 3, where it is securely held. I then take the length I) and place it over the end of the pipe ct, letting its 0 end engage with the corrugated end of the collar l), where it is firmly held.

It will be observed by this construction that I am able to utilize a full length of pipe without cutting it, and thereby rendering it useless for any other place than the one for which .it is cut.
